A positive displacement, recirculating Roots-type rotary gas compressor which operates on the basis of flow work compression is disclosed. The compressor includes a pair of large diameter recirculation conduits (30 and 32) which return compressed discharge gas to the compressor housing (16), where it is mixed with low pressure inlet gas, thereby minimizing adiabatic heating of the gas. The compressor includes a pair of involutely lobed impellers (12 and 14) and an associated port configuration which together result in uninterrupted flow of recirculation ...
A positive displacement recirculating rotary compressor comprising: a housing having two mutually opposing cylindrically curved interior side walls; said housing including a gas inlet port at one end located between said mutually opposing cylindrically curved side walls and a gas outlet port located at the opposite end of said housing from said inlet port and also located between said mutually opposing cylindrically curved interior side walls; said gas outlet port opening into a discharge manifold having a gas discharge port; said housing further includi...
